Having actually looked at the bulbs, as opposed to being told what they are

Ok, so 175W won't overload your dimmer, but others have pointed out if
you run them dimmed, you'll likely still be paying more than for having
a single larger bulb at full brightness. That said, the only room of the
house where I don't have CFL lamps is the lounge where I have a
dimmer+filament, the only place I find I need it adjustable ...
